    I have a question(maybe stupid) that concerns with digital color meter which we can find under utilities.And the question is : Is digital color meter like zooming in the screen?I mean can we find if we have some defective pixels by using this utility?I ask this because i want to realise if these 2 marks i see on my imac's screen are dead pixel or dust behind the glass.I try to look at them as closely i could and realise that the pixels are working fine.

    No, Digital Color Meter won't reveal dead pixels -- it only "sees" the
    contents of the VRAM buffer containing the data that's supposed to
    appear on the display. D.C.M. has no way of telling whether the data is
    displayed correctly or not.

    If the pixel you go over is different from what you see on the screen, it's dust, dead, or stuck... no way to tell which though, those are "hardware", not software.
